MACHENE FOR DRESSING HEMP, FLAX, AND OTHER FIBROUS SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 290,494, dated December 18, 1883.

Application filed March 12, 1883.

T aZZ whom it may concern:

Be it known that I, Tnnononn Tnnow, a citizen of the United States, and a resident of Nioholasville, in the county of Jessamine and State of Kentucky, have invented certain new and useful Improvements in Machines for Dressing Hemp, Flax, andother Fibrous Substances, of which the following is aspecification. a

My invention relates to improvements in machines for buckling or dressing hemp, flax,

and other similar fibrous matter, and has for its objects to provide novel means for causing the hackle-teeth to continuously advance into and recede from the suspended hemp 5 to provide novel means for stripping the hackleteeth of adhering tow or other matter, and to provide a novel device to feed the hemp gradually into position for dressing, and at the same time move it laterally for causing the hackleteeth to pass through different fibers alternately.

The invention has other objects, all of which will be hereinafter set forth.

The objects of my invention I accomplish by the mechanism hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal elevation of a hemp-haekling machine embodying my invention. Fig. 2 is a similar View of the op posite side of the machine. Fig. 3 is a sectional plan on line a; m, Fig. 2. Fig. 4. is a detail transverse sectional view on line at to, Fig. 5, of the zigzag-grooved sliding box for vibrating the feeding-clamps. Fig. 5 is a'de tail plan view of the same device shown in Fig. 4. Fig. 6 is a detail end elevationof the clutch-collar on the hacklewheel shaft. Fig. 7 is a detail elevation of the clutch and pulley device on the hackle-wheel sh aft for stopping and starting the mechanism for operating the feeding-frame toward and from the hacklewheel. Fig. 8 is a transverse section of the feed-clamp, andFig. 9 is a detached perspective view of the feed-clamp and its supporting uprights.

A A represent the longitudinal bars, and A A the legs composing the supporting-frame of the machine.

.13 represents a driving-shaft, suitably jour- (No model.)

naled in boxes within the lateral extension A of the frame.

B represents a driving-pulley, and B a transmittingpinion, both being mounted on shaft B.

O is a skeleton wheel, composed of hubs C G and slotted arms 0' G, and mounted on a shaft, D, suitably journaled in boxes at a on the bars A A of the supporting-frame.

D is a'large gear-wheel keyed to shaft D, and meshing with pinion B, by which it is driven.

E E represent transverse bars armed with hackle-teeth e, and mounted at their ends on slides E E, which reciprocate in the slots or ways 6 of wheel-arms G.

b b are metal straps or loops attached to the slides E, and moving upon plates 1), which are secured to the front faces of the arms G. Straps I), sliding upon plates 1), cause the slides E to move freely within the slots close upon their seats of motion.

(Z dare rollers pivot-ed upon the slides E.

F F represent suitable rollcr-guides atboth sides of the machine, formed by the bars ff, secured to frame-bars A. Guides F are preferably perpendicular between their curved inlets and outlets, so that the operation of the hackle-teeth upon the hemp will be in a downward str. ight line, and a long thorough vertical pull or passage through it obtained. Rollers d travel in guides F to properly advance and retract the hackle-teeth in their rotary movement. The arrows in Figs. 1, 2, and 3 indicate the-direction of movement of wheel 0.

c c are angular metal straps securing and connecting the outer ends of the bars forming the slotted arms 0'.

' G G represent transverse bars mounted on slides G at their ends, which travel in the slots or ways 6 of the arms 0 upon the hacklebar slides E.

g g are rollers pivoted upon the inner ends of slides G, and traveling a portion of their rotary movement in a cam-guide, g, to advance the bars G over the hackle-teeth e, as they leave the hemp, to strip or clean them of tow or other adhering matter. Hackle-teeth e are preferably set at an angle to the bars E, wherebythe teeth are caused to project downward 0n approaching the hemp, so that they may enter it as early as possible in their rotary movement anddraw it toward-them, andholding it more firmly than if arranged radially.

H H represent the basebars, and II II the uprights or posts composing the hemp feeding The butts can be easily dressed by clamping the dressed portion-between theclamping-b'ars From this operation more long hemp andless tow would result than by any other method or by machines k'now-n to me.

t t arestrengthening-strips of metal in-the clampin'g bars I I".

z" z" are strips of rubberor cushioningmaterial, secured by andbetween metal strips i31 to the clamping inner faces of clamping-barsI I; making strong tenacious hold for the hemp.

Jis-a-stri a of muslin or other fab'ric'covering the rubber strip on the bar I, passing berubb'er firmly in place.

J" J are straps-or yokes, pivotall'y secured'to the ends of the bar I and made-to sw-ing upon th'eadj'ustable-bar T. Bar I slides within the yokes J to be clamped firmly upon-the hem-p placed between it and the bar I by hand press-- ure-screws j j.

Kare studs or pins at th'e end'sof bar I, on which the clamppivotsin bearings 75, madein' the upperends of bars K. Bearings k are preferably open slots, as shown, so that the clamp can be readily attached and detached. The feed-clamp is held in the inclined posi-- tionshown for the proper suspension of the hemp by one or more bolts, n, as in Fig. 2, which maybe made to enter openings in the ends 'of the lower bar, I, and kept in" position by the movable spring 0%. Bars K are pivoted intermediate of their ends to the uprights H.

L is a roller suspended from bracket, L, at the lower end of one of the pivotal bars K.

Zis asliding box, mounted upon an out ward-extension, M, of one of the main-frame bar-SA.

Z is an irregular or zigzag groove made in box Z, into which the roller L' issuspended.

m is a pitman' attached atone endtothe box Z, and connectedat its other end withthe gear wheel D. Box Z isreciprocated' by pitm'a n m, its zigzag groove Z causing the roller L to-movelaterally and the pivotal bars Kto vibrate; The lateral movement of the bars K causes the clamping-bars I I, mounted thereon, tocarry the hemp suspended therefrom to mo ve in diHerent paths of travel of the hackleteeth, resulting in a thorough dress of the hemp.

N is a transverse tie-board connecting the uprights H of the feeding-frame.

O O are vertical fenders attached to back board, N, to prevent the entrance of hemp suspended from the clamp-bars into the slotted arms 0 of the hacklewheel, that would clog and choke them, thereby interfering with the operation of the sliding parts of thehackleteeth and stripper-bars.

P I represent ropes attached at their ends to the feeding-frame and connecting with a winding shaft or drum, 1), suitably journaled at the rear end of the machine.

Q is a belt connecting cone-pulleyR or shaft pwith driving cone-pulley Q or wheel-shaft D.

S represents an ordinary clutch device for bringingloosecone-pulley Q into and outof engagement with the revolving shaft D.

S is'an' ordinary clutch-lever for bringing into and out of gear the clutch devices. It is provided with acam projection or ridge, 8, at its free end, which comes in contact with an :inclined face or cam projection, s, on one of ithebase-bars II of the feeding carriage or frame, to automatically shift said clutch-lever and stop the winding operation of ropes]? P when the feeding-carriage has approached the i desired position toward thehacklewheel.

neath the strips to assist in holding the=said T T are inclined tracks, up on which the feedingcarriage moves to elevate the clamp-bars as they approach the hackle=wheel, and place them as near as possible to the hackleteeth without coming in contact with them. These inclined tracks permit and aid materially in the ready withdrawal or backing of the feedcarriage from action, which is accomplished by the attendant or operator. The back board or tie-board N approaches close to the points of the'hackle-teeth in the forward movement of the carriage, and prevents the hemp from sliding off or retreating from said teeth dill" ing their operation upon it.

U represents a platform at the rearendof the feedcarriage for the operator to stand uponin adjusting the hemp to and from the clamping devices.

The operation of my machine is as follows: Thehemp to be dressed is first clamped by its butt-ends between the clamping-bars I I, permitting it to hang freely in front of the hacklewheel. The hackle devices being set in motion" and the clutch-lever S shifted so as to bring thewindingshaft p into motion,the feedcarriage is then slowly drawn toward the hackle-wheel, whose teeth advance gradually into the hemp, pass through and out its fibers, and recede therefrom at the lowermost point of travel of the outer ends of the wheel-arms O. The advance of the feed-carriage-having been retarded by the adjustment of the clutch device, and the hemp sufficiently dressed, it is then returned to its normal position out of the path of the hackle-teeth, and the handscrews of the clamp-bars I I adjusted so that said hemp may be extracted therefrom, and

that part of the hemp previously held between said clamp-bars subjected to the same operation as above. The long, steady, and successive passage of the hackle-teeth through the hemp insures a perfect dress, and a very limited amount of tow results therefrom in the operation of my machine.

I claim 1. In a machine for dressing fibrous substances, the combination, with the revolving shaft, the radial arms having slots, the toothed bars arranged to reciprocate in the slots, and having frictionrollers at their ends, of the vertical guides F, having curved inlets and outlets, substantially as shown and described.

2. In a machine for dressing fibrous substances, the combination of the slotted arms, the hackle-teeth bars, the stripper-bars, and means for reciprocating the hackle-teeth bars and advancing and retracting the stripper-bars over the hackle-teeth, substantially as described.

3. In a machine for dressing fibrous substances, the combination of the adjustable clamping-bars I I with a carriage carrying said bars, a winding-drum, a rope connecting the drum with the carriage, and a clutch for operating the drum, substantially as and for the purpose described.

4. In a machine for dressing fibrous substances, the combination of a revolving wheel or cylinder, hackle-teeth carried thereby, a feed-carriage, ways on whichthe carriage may move, clamping-bars I I, upright pivoted bars K, a grooved box, Z, anda connection between the upright pivoted bars and the grooved box, substantially as and for the purpose described.

5. In a machine for dressing fibrous substances, the combination of hackling devices, a feed-carriage, means for advancing the carriage toward the haclrling devices, clamping bars I I, mounted on the carriage, the back board, N, and fenders O, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

THEODORE TEBOW.
